Application

Vickers hardness of ceramicsand hard metals standard reference material (SRM) is intended for calibrating all hardness and microhardness testing machines. It involves creating a Vickers indentation and subsequently measuring it using a microscope.

Features and Benefits

• Accompanied with certified values for individual diagonal lengths, average diagonal length, and average Vickers hardness are provided.
• The NIST certificate is provided with expiration certificate, storage, handling,use, and maintenance instructions.
